1. What is an instrumentation amplifier and what is it mainly used for?
An instrumentation amplifier is a high-precision amplifier designed to amplify low-level differential signals with high input impedance and high common mode rejection ratio (CMRR), and is commonly used in scenarios such as medical equipment, sensor signal processing, and industrial measurements.
-
2. What is Common Mode Rejection Ratio (CMRR) and why is it important for instrumentation amplifiers?
CMRR indicates an instrumentation amplifier's ability to suppress common mode signals, with higher values being better. A high CMRR is especially important in noisy environments to ensure that the amplifier primarily amplifies differential signals and is not affected by common mode interference.
-
3. What are the main application scenarios of Op Amps?
Operational amplifiers are widely used in signal conditioning, voltage follower, filter, comparator, integrator, differentiator, precision level shifter and other circuits, which are widely used in consumer electronics, industrial automation, and instrumentation.

4. What is the effect of the op amp's out-of-range voltage on accuracy?
An out-of-phase voltage is the difference in voltage at which the output is not zero when the signal at the input is zero. A large out-of-phase voltage reduces the accuracy of a system, especially in high-gain applications, and selecting an op amp with a low out-of-phase voltage can improve accuracy.
